Hello everyone,

We have received a plot of land with a small transformer station located at one corner. We have considered various options but haven’t been able to decide on anything yet. This is our first build, so perhaps others might see possibilities or ideas we haven’t thought of.

Development Plan / Restrictions
Plot size
Approx. 21m (69 feet) wide x 30m (98 feet) long – minus transformer station = 570 m² (6135 sq ft)

Slope
Very flat, about 1m (3.3 feet) difference across the entire site.
Road is the highest point, then gently slopes down by -1m (-3.3 feet)

Floor space index
See plan

Floor area ratio
See plan

Building envelope, building line and boundary
Marked on the plan, distances according to Baden-Württemberg state building regulations

Edge development
Non-residential building. To the right side of our plot, the planned residential building with a 3m (10 feet) garage on the neighbor’s boundary is shown.

Number of parking spaces
2 per dwelling unit

Number of stories
2
Max. building height 6.00m (20 feet)

Roof shape
Open, as far as I have read, all roof types are allowed within the corresponding angles

Architectural style
No specification

Orientation
Flexible within the building envelope

Maximum heights / limits
Max. building height 6.00m (20 feet),
Full building height 8.50m (28 feet)
Max. deviation of 0.50m (1.6 feet) allowed for single-family houses

Other notes:
Existing transformer station at the top left corner.
Setback areas marked on our plot.
Currently surrounded by an earth berm that the utility company temporarily placed on our land for renovation – it will be removed.

Client Requirements
Style, roof form, building type
We are quite unsure. A modern townhouse would be great; I like spacious, bright rooms. Flat roofs are less preferred due to waterproofing concerns. Our plan: a single-family home, possibly with two dwelling units for future renting or an immediate granny flat for a home office.

Basement, floors
1 basement planned for hobbies and home office; 2 full floors possible at a max. height of 6.00m (20 feet)?

Number of occupants, ages
4 people (possibly 5 if we’re lucky), 2 adults around 40 years old, 2 children aged 2 and 5 years

Room requirements on ground floor and upper floor
Ground floor: open living room combined with dining area + kitchen + home office or alternative bedroom for older age.
Shower on ground floor.
Office: dedicated home office space, real workspace usage.

Number of guest stays per year
About 5–6

Open or closed architecture
Preferably open, lots of light, I like floor-to-ceiling windows. Still looking for inspiration, ideas from what is common today and what we might be missing.

Modern construction, white bright rooms, lots of natural light, sun, rather bold, extraordinary.
So far, we might be a bit conventional.

Real kitchen, my wife cooks and bakes, with an island and breakfast bar for quick meals or takeaway pizza.

Number of dining seats
6 for daily use, 10 for parties.

Fireplace
Yes, integrated would be sufficient.

Music/Stereo wall
No specific plans at the moment.

Balcony, roof terrace
Balcony planned facing south, intended to serve as sun protection.

Garage, carport
Double garage at least 6x6m (20x20 feet) or larger to accommodate bicycles and children’s toys.
How would you position the garage? I’m not fully satisfied. A large garage would be nice, maybe even 8m length (26 feet) for a caravan? Though probably too big to fit.

Lawn/garden for playing football and children to run around.

House Design
Planner from a construction company

What do you like most? Why?
Practical layout with smooth transition to the outdoors from the living room, open roof, exposed beams would be nice but complicated and expensive due to double-layer construction.

What do you dislike? Why?
South elevation top, balcony design, window depths, and arrangement – we are unsure. It lacks some flair in the layout.

We welcome ideas or suggestions – do you see things or approaches that we don’t, new perspectives or things we might have completely
forgotten or overestimated?

Cost estimate according to architect/planner:
Open, quote pending

Personal budget limit for the house including fittings:
Still in the budgeting phase and not fully clear yet

Preferred heating technology:
Open to anything – underfloor heating is mandatory

If you had to give up something, what features or extras
-can you go without:
Studio

-can’t you do without:
Home office

Why is the design the way it is now?
E.g., number and function of rooms, competitor offer as a basis, necessity of the layout due to the plot

What is the most important/fundamental question about the floor plan in 130 characters?
What implementation ideas do you have that we haven’t considered to optimize the plot use? Ideas for the house to inspire or ground us welcome. First build.

Here is the progress of the planning. Single-family house with basement, approximately 200 m² (2,150 sq ft).
2 children, 1 guest room, 1 home office. Currently planned with a basement.

Currently planned ground floor. Garage driveway on the side, house positioned sideways, garden area maximized on the south side (about 10 m (33 ft) from the house).

Current planned upper floor. Master area includes walk-in closet, bathroom, and bedroom. 2 children’s rooms, 1 guest/multi-purpose room/game area/studio upstairs, storage room and a small second shower and toilet for the children. Balcony serves as shading and for kids.

Section. Ground floor ceiling height 2.85 m (9 ft 4 in), upper floor knee wall height 2.65 m (8 ft 8 in), attic open upwards.

Developments: The office on the ground floor is planned to be large enough to be converted later into a master bedroom on a single floor, barrier-free. Or if we divide the house into two separate living units for the children, for example, one upstairs and one downstairs. Since my wife wants a utility room and pantry, the kitchen will move to the southeast, and we will have a large room in the south. We also found out the room at 4.50 m (15 ft) wide is too narrow and doesn’t feel right, so we want to increase it to about 5.50 m (18 ft).

The idea is to place the kitchen in the northwest, so you can look out in front of the house from the kitchen, and have the living area running from north to south and west-facing windows/terrace. The issue is we want the living area to be wider, otherwise it feels too narrow at 4.50 m (15 ft). With this layout, the utility room and pantry become challenging, and the office would likely need to move to the southeast. Alternatively, we could keep the room with an L-shape and separate it later in life. Possibly, however, the living-dining area would then feel too spacious? In that case, I would definitely need to move the office to the basement.

On the upper floor, there is still the question if we could rotate the master area, which would allow us to orient all three rooms fully to the south and remain flexible. The master bedroom would then face south and be separated upwards in case I snore loudly at night or something.

South view with balcony. Is this a good shading solution? We are planning for somewhat taller windows, about 2.30 m (7 ft 7 in).

North view with driveway. The garage would be located directly in front, reducing the garden size to about 9 m (30 ft) to the property line. The driveway is still straight and feasible.

We would appreciate any suggestions or things you notice that we might have missed.
I welcome ANY ideas or input and I am already looking forward to the second and third time building a house 😉

Best regards, Markus

Cross-section. Lower floor height 2.85m (9 ft 4 in), upper knee wall height 2.65m (8 ft 8 in), roof open at top.

These dimensions are not the floor-to-ceiling heights but the clear structural shell heights without insulation, screed, and flooring. For insulation, screed, and flooring, you should subtract about 20cm (8 inches) from your measurements. Once finished, the basement will also not be 2.5m (8 ft 2 in) but closer to 2.3m (7 ft 7 in).

Thanks for the info, this is our first time building, so I will double-check.

Hello, we’ve made some progress and developed a few options, but we are still undecided about the positioning of the garage/driveway and whether to place the kitchen at the front or have the entire living and dining area there.
Since it’s raining today anyway, I’m sharing the latest developments and would appreciate any comments or ideas. 🙂

Best regards, Traufgänger

I am surprised by two things: first, the long planning duration, and second, that I apparently haven’t asked in this thread yet what materials are being used for the construction. On one hand, I see exterior walls in the classic solid construction thickness of 365mm (14 inches), but on the other hand, there are unusual interior wall thicknesses and dimensions that seem inconsistent.

When looking at the floor plan design, I get the impression of being trapped in love with the visualization of a still unsuccessful draft, whose “spirit” somehow has to be preserved, while a sort of room-layout puzzle is being played to make it work. This is a typical phenomenon in drafting plans by underqualified designers. Probably, the supposedly higher fee investment in an independent architect would already have paid off twice over by avoiding the interim increases in construction costs.

I recommend a relaunch and fresh start with a professional planning methodology. A patchwork approach—which is the exact opposite of clean code—dramatically increases the risk of construction defects due to complex connection details in every corner and joint. And with the further refinement of the design along this unsuitable path and growing frustration, the project is more likely to turn from wine into vinegar than for the power of prayers to untie the Gordian knot.

I think it is a positive development that the building line is now being respected. Perhaps this was one of the reasons for the delays?
